AT89C52_TEMPERTURE_MONITOR

FAT32文件系统 基于LPC2200，前后台环境，可自己修改适配于各种RTOS。 验证环境: 搭载LPC2200的SmartARM2200开发板,使用该板上的SPI总线利用该程序读写SD卡 由于试验的SD卡比较特殊,1簇仅1扇区,所以不排除该程序对于非该情况的出错可能(FAT32 file system based on the LPC2200, the environment around Taiwan, can modify their own adaptation in a variety of RTOS. Verification environment: SmartARM2200 with the LPC2200 development board, using the on-board SPI bus of the use of the program to read and write SD card SD card as a result of testing is rather special, 1 cluster only 1 sector, so the program does not exclude the situation for non- error may)

超声波浓度计 采用混合信号处理芯片c8051f021与12864与485芯片同时输出4-20mA电流(Ultrasonic densitometer mixed signal processing chips c8051f021 and 12864 and 485 chips while the output 4-20mA current)

相信大大家都用过DS18B20A，我自己也用手写了个玩玩(Believe that we all used DS18B20A, I have to play with a hand-written)

51单片机驱动12864及1602程序，带有proteus仿真(51 microcontroller drive 12864 and 1602, with proteus simulation )

(msp430g2553)正弦信号，一方面被adc采集获取其幅度信息，另一方面经比较器变成方波，经Timer捕获获取其频率，然后控制SPWM信号的频率与幅度，使输入与输出同幅同频变化。((Msp430g2553) sinusoidal signal, on the one hand is to get its amplitude information collected adc, on the other hand by the comparator into a square wave, captured by Timer obtain its frequency, and then control the frequency and amplitude SPWM signal input and output with the same amplitude frequency variations.)

本文件包含7章理论学习和4章手动实验，内容涉及SPI协议，动态扫描，串口传输，电机控制等(This document contains 7 chapters of theoretical learning and 4 chapter manual experiments, involving SPI protocol, dynamic scanning, serial port transmission, motor control and so on.)

用IIC 控制MP3播放、调音量、选曲，方便MP3应用在嵌入式系统。(MP3 player with IIC control, adjust volume, selections, easy MP3 applications in embedded systems.)
